About the Python Dict to JSON converter
Parse Python literal syntax
The converter uses a local Python dict parser rather than executing Python code. It supports curly dict literals, dict constructor syntax, strings, lists, tuples, None, True, False, inline comments, and numeric forms such as hex, binary, octal, underscores, and scientific notation.
Normalize Python values into JSON
None becomes null, True and False become lowercase JSON booleans, and tuples are converted to arrays. Comments, original quote style, and dict constructor formatting are discarded because the output is formatted JSON data.
FAQ
Common questions and answers about this topic.
What is the difference between Python dict and JSON?
Python dictionaries use single or double quotes for strings, True/False for booleans, and None for null values. JSON requires double quotes, uses true/false, and null. This tool automatically handles these conversions.
What Python syntax does this converter support?
This converter supports curly brace dict literals ({'key': 'value'}), dict() constructor syntax, single and double-quoted strings, nested dicts and lists, tuples (converted to arrays), None/True/False, numbers with underscore separators (1_000_000), hex/octal/binary literals, scientific notation, and inline comments (#).
Can I customize the JSON indentation?
Yes, you can adjust the tab width (2 or 4 spaces) or switch to tab-based indentation using the formatting options above the output panel.
How does the tool handle None, True, and False?
Python's None is converted to JSON's null, True becomes true, and False becomes false. These are automatically mapped to their JSON equivalents during conversion.
Is my data sent to any server?
No, the Python dict to JSON conversion happens entirely in your browser. Your dict input is parsed and transformed locally via JavaScript and never leaves your device.
